Choose all of the statement below that are correct concerning mechanical advantage. you apply a force of 50 n to a shovel. the shovel applies a force of 500 n to the weed. the mechanical advantage is 10. you apply a force 10 n to a lever which forces a television to lift with a force of 20 n. the mechanical advantage is 200. it is possible to use a simple machine and gain no mechanical advantage no simple machine can every supply a mechanical advantage. if you wanted to lift a 50kg object up 5meters, you would have to supply a mechanical advantage of 10.

1).  You apply a force of 50 N to a shovel. The shovel applies a force of 500 N to the weed. The mechanical advantage is 10.

TRUE

As we know that mechanical advantage is given as

2).  You apply a force 10 N to a lever which forces a television to lift with a force of 20 N. The mechanical advantage is 200.

FALSE

As we know that mechanical advantage is given as

3). It is possible to use a simple machine and gain no mechanical advantage No simple machine can every supply a mechanical advantage.

FALSE

It is possible to have no mechanical advantage in those cases where applied force is same as the force to pull up.

4). If you wanted to lift a 50kg object up 5meters, you would have to supply a mechanical advantage of 10.

FALSE

It is not essential to apply MA = 10 to pull upwards a given object
